The AirTAC Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X60-40S is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 60mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The ACEJ100X60-40S is a double acting, adjustable-stroke compact cylinder built to ISO 21287. Its 100 mm bore delivers 3927 N push and 3769.9 N pull at 0.5 MPa, rising to 5497.8 N push at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. An external stop screw trims the 60 mm extend stroke anywhere inside the ordered 40 mm window, giving a usable range of 20-60 mm without changing the air supply. The hard-anodized aluminium body and S45C hard-chrome plated rod suit 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, running 30-500 mm/s.
Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 100 mm bore fits heavy presses and clamping fixtures where a full-length profile cylinder cannot. Plan on roughly 2356 N (about 240 kg) of real work at 0.5 MPa rather than the full rating, which means it lifts about 120 kg vertically with a 2:1 margin. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots, and fixed TPU bumpers absorb end-of-stroke energy at both ends.

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
The 3927 N push at 0.5 MPa presses bearings into housings on an automotive assembly line, with the 40 mm window letting technicians trim the 60 mm stroke down to 20 mm for shallow press depths.
A 100 mm bore clamps mould halves on a plastics machine; the short ISO 21287 body slots into the tight platen space where an ISO 15552 profile cylinder would be twice as long.
Lifts about 120 kg vertically with a 2:1 margin at 0.5 MPa, pushing pallets onto a conveyor, while the fitted -S magnet and CMSE switches confirm full extension at each cycle.
At 3927 N push at 0.5 MPa this 100 mm bore sits near the top of the ACEJ range; step down to the 80 mm bore (2513.3 N push) for lighter clamping, or to the 125 mm bore (6135.9 N push) when the load demands more. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke detection.
Quick checklist
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa it pushes 5497.8 N and pulls 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 60 mm extend stroke by up to 40 mm, so the working range is 20-60 mm. It is double acting with a 1/8" PT port and a 20 mm rod with an M12x1.75 female thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and gantries. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly in the body slots. FA flange and LB foot mounts bolt to the standard face, and fixed TPU bumpers at both ends absorb end-of-stroke energy; they do not hold or brake a load.
